Apple is expected to face a decline in sales, particularly in the Chinese market, as investors eagerly await the addition of generative AI in the upcoming iPhones. The company's shares have underperformed compared to other tech giants, dropping over 10% this year. Analysts predict a 10.4% decline in iPhone sales in Q1 2024, the sharpest decline in three years. To address this, Apple is in talks with Open AI and Google to incorporate generative AI features in the next iPhone series. Additionally, investors are looking for updates on Apple's stock buyback plan and the performance of its new product, Vision Pro.
